I can't say that I know for sure but it really shouldn't be a problem as some of the `63s came with 260 V-8s. Sourcing original parts might be a problem but finding new replacements mounts should be simple. I'd start with one of the larger Mustang supply companies.

In order to transplant a 260/289/302/351w into a 62-65 6 cyl falcon or ranchero you need to consider the weight and torque of the replacement engine. In addition to replacing the motor mounts and mount stands, you will need to change over the suspension components to the heavier duty V-8 tie rod ends, ball joints, upper control arms, coil springs, etc. You will also need to upgrade the brakes as the stock 6 cyl drum brakes are insufficient. If you can get your hands on a copy of the Ford parts manual or know someone who can cross reference the numbers for you, you should be able to use mostly 65 Mustang parts. A large portion of early Mustang mechanical parts are Falcon and Fairlane part numbers. If you can find someone who has a V-8 Falcon, try to get accurate measurements for the location of the motor mounts. This should save you some headaches. You will need to find the rear differential including housing, axles, and brakes for a V-8 Falcon (I seem to remember it's an 8-inch) or upgrade to a 9-inch rear end complete assembly. The stock 6 cyl rear will not hold up to the horsepower and torque difference of the V-8. The V-8 cars are 5-lug as opposed to the 4-lug 6 cyl cars so if you want matching rims be sure to upgrade the front to match the 5-lug rear-end.

The easiest way around all of this is to sell your 6 cyl Falcon and find one that is a stock V-8 car. You'll probably save a lot of money and time.

I have a 62 Ranchero that has a 302 in it and wasinstalled 20 yrs ago with a conversion kit. It includedspecial motor supports and headers and other parts.I don't remember the manufactur. I think Hedman stillmakes the headers, they were in the Summit Catolog.I'm not sure if it is still made.

The editor of Car Craft did several articles on the conversion he did on his 63 Falcon (which I am told was stolen a few months later). His articles covers the suspension changes step by step with a parts list. The required (complete) motor mounts are found on a 63-65 Falcon/Comet and 64-66 Mustang V-8 (the 66 Mustang style is the best). Fabricated mounts/crossmembers for a C-4 trans can found at several online vendors dealing with the early Falcon/Comet.

I do not have the exact month/date of the articles on hand but post your request on the Car Craft web site and someone can provide that info. Web sites such as www.ford-forums.com have covered the convestions an endless number of times.

Finding the issues on ebay will be easier than getting a reprint from Car Craft most likely. Our back issues department wont have them because they only carry about a year. Have you checked their web site? It's most likely too old to be on there though.

For the people who have contacted me in regards to the Car Craft article covering the conversion: Had a major upset at this end (notice of pending foreclosure) and haven't gotten a chance to make copies of the article for those who asked. I hope to make some recovery next week timewise and send out said copies.

63 falcons and comets could be had with v-8 engines from the factory. if you can acquire the factory v-8 car, then your basic problems are solved. it's just nuts and bolts from there on out. you might also check out 62-65 v-8 fairlanes and mercury meteors for pieces and parts that would help you in this conversion.
